These ITP ATR tires really hook up in top soil and grass. The do very well on hard clay too. In comparison to the OE Dunlpos, the Dunlops are like riding a car in the rain. Trying to bang this easy left turn on a mountain logging road and the rear didn't break loose. Hit the bank and a tree at the same time and pushed the light guard ring into the fender to the point of popping off the first 3 fasteners of the black flap. My new machine is now getting her first sighn of a personality. Pulled out the tow strap and yanked it out and bungeed the flap.
I have learned with these tires, if you want to sling the rearend around in anything but gravel or mud, you better mean it.

Oh. I have ordered my new front bumper and fasteners from RonAyers, as well as a Service manual. The protection integrity for that side of the bumper is gone. If it takes another hit it will destroy my headlight.

I will be taking my old one to some of the fabricator\welders at my job to see about a duplicate made up out of a stronger material. I believe it does need to bend to avoid transfering the force through the rack to the shock towers, but it could have been a little stronger. Perhaps a bit thicker material?

 

Rock,

Hope the quad was the only thing that got hurt and that you weren't injured. Just another case in point of why we need to wear helmets when riding. You never know when your going to end up somewhere other than where you pointed the quad[img]i/expressions/face-icon-small-wink.gif[/img]

 

Yep, I noticed the same thing with the ATRs in combination with the IRS on my Griz. I have to work harder to break the rear end loose now because those tires really stick. I can get them to break but sometimes I have enough lateral force going on to raise the inside front tire off the ground during my sliding turn.

Overall I’m happy with the feel and performance of the tires in all conditions except mud where they probably don’t function as well as the stock tires did. Anyway if I plan to do a lot of riding in muddy conditions I just switch to my 589s.

 

Well you guys now that you had some time on the ATR's what do you think of them, are they as tough and great handleing as people say or are things exaggerated?????

 

I had Bear Claws on my 2000 Kodiak 4X4 Auto. That and the fact the Kodiak's front diff super slip is the worst in the industry gave me the excuse to sell and get the P650. I wanted it the day I heard of it.
The claws beat me to death. They will run flat. They have let me down in steep hard to medium hard pack situations many a time. They bump steered un-godly.
Enter the ATRs'. No bump steer. As I posted above they grip more than expected at times. They steer much better than the Dunflops. I run 4 psi front and 5 psi rear.
There seems to be an industry trend towards mud tires for the all purpose needs. NOT! Those long lugs will let you down in other situations and beat you to death. The Titan 589's are the only tire I would say would be safe in any situaton. But the ride comfort suffers. I avoid Deep mud holes. Only if there is no other way. And with the ATRs I'll chance it. I have a rope and a winch for the emergency.

 

They are tougher and they do handle better than the stock Dooflops. I will say this though. Most of what you hear is somewhat exagerated.
+'s
Good tires on hardpack.
Good in snow.
Good in the rocks. Large rocks only, they are terrible in loose 3-4" rock.
Better cornering than stock but not as good as a lot of people claim.
A lot less resistant to punctures.
So far I have 200 miles on mine and they seem to be wearing reasonably well. I have however removed a couple of large chunks from the tread blocks.

-'s
Not as good as the stock dunflops in sand.
Shorter, less ground clearance.
No matter what pressure I run they seem to ride rock hard compared to the stockers.
All we get here is slick surface mud and they are better than stock but nothing to write home about.
Squirrelly at high speeds (I actually had to dynamic balance mine to make em safe and they are still squirrelly)(and yes I have been all over the map with toe settings!)

Overall I'm not dissapointed in my purchase but for my next set I intend to try something else.

 

Reporting on my experience with the IRS Grizzly I find the ATRs to be an excellent firm terrain tire. It’s a great trail riding tire (i.e. Hatfield McCoy style trails) and handles obstacles (logs, rocks) really well.

The shape of the cross section of the tire (oval with wrap around tread) and radial design give it better than average handling in rocky or otherwise rough situations. I also find off-camber handling is better than average as they are more resistant to sliding sideways (which is also why it’s harder to power slide with them).

They also have a better feel on pavement than any other tire / ATV combination that I’ve tried so far. I have not experienced excessive out of balance / out of round conditions that others have (although I run slime in all my tires so they are probably impossible to balance and stuff like that in your tires would not be good if you want to try and break any land speed records).

The ride is rougher than the stock tires (as it will be with any tire sturdier than the 2 ply construction of the stock tires), however they are nearly vibration free when compared to other tire types (on pavement or hard pack).

They are not good for serious mud work and will probably not work well in snow (I’ll find out next winter) as stock tires. I have not experienced riding in sand (none close to where I live) but they probably wont work well there either.

However the serious ATV enthusiast should have at least 2 sets of tires mounted on their own wheels to allow for easy changing to match the riding environment. Until something better comes along the ATRs will be part of my set and will probably spend more time on my ATV than any other (since a lot of my riding is done in a field / woods environment).

 

I just want to thank everybody for the feed back on the ATR's, I'm ordering a set of ATR's and a set of Douglas 190 Red Labels wheels as we speak. I can't wait to try them out..

 

WOLLEY... what rims do you have the ATR's mounted on ??? Mine are on new Magnum Billets, & I think with the welded centers, that they aren't very true... I spin balanced mine, & at 9 # PSI, I still had a high speed wobble... after dropping the air pressure to 4.5 PSI, I'm reasonably happy with mine... they went through some very rocky trails, with only a very minor bruise on one sidewall, & no rim damage... the time before, I was running 23" 489XT's, on the front, & bent up my rim beads pretty bad...WAM

 

I'm running them on stock rims. I originally jacked up the wheeler and ran it in 4WD to find out why these things shook so bad. It almost shook it self off the jack stands. No way I could tell whether it was an out of round condition or just imbalance. Took the wheels to a couple of motorcycle shops to bubble balance them because I was told that the wheels would not fit on a dynamic balancer. Turns out they won't fit on a motorcycle bubble balancer either. Any way after convincing a tire store that they would fit on the Coates machine they spun them and I was able to see that they were indeed straight just horribly out of balance. One wheel took a total of 8 ozs to bring it close. It would have been nearly 20 ozs if I had tried to use stick on weights rather than rim weights. That is a bunch for such a small wheel. This eliminated the shakes but it did nothing for the high speed wobble. Ever ridden one of the older street bikes with spoked wheels and experienced death wobble? Very similar. They only do this on dirt. I figure they are tracking in the small irregularities of a dirt trail.
BTW I run 4.5psi in all four. Any more and they are too skittish at high speed and ride like steel wagon wheels.
